A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical ...

Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal ...

Abstract: Abruptly time-varying materials enable unprecedented control over electromagnetic (EM) wave properties. This work develops a full-wave finite-difference time-domain (FDTD) framework to ...

Abstract: The imaging polarization sensor (IPS) can provide high-accuracy, robust, and fully autonomous navigation information for underwater unmanned platforms. However, the polarization images in ...
